This makes a lot of sense. I hadn't thought of it that way. Killing the body can't kill the bit of soul in it, because it's anchored here by the other bits of soul. However, it's interesting to think it works in reverse. You *can* kill one piece of the soul as long as it's a Horcrux and not the "active" soul. But you can't kill the "active" soul while Horcruxes stil remain.

What then would be the point of having more than one Horcrux? I suppose just extra insurance. But if it's true that killing the body doesn't kill the active soul, then it's theoretically possible to die, allow your active soul to float around for a bit while someone brews you up a body and complete the circle over and over indefinitely, since you don't have to utilize a Horcrux each time you come back to life. Fun!
